- Brief Summary
This randomized, cross over study aims to find out the benefits of delivering triple therapy using a single ELLIPTA® DPI (fixed-dose combination triple therapy) versus delivering triple therapy using two different types of inhalers (open triple therapy) including DISKUS® with HandiHaler® to subjects with COPD. Correct inhaler use, critical errors and performance attributes will also be assessed. Approximately 240 subjects with COPD will be randomized in the study. The study will be conducted in 3 visits and will be completed in approximately 56 days. At Visit 1 (Day 1) and Visit 2 (Day 28) subjects will be randomized to receive a placebo ELLIPTA inhaler once daily (QD) or a placebo DISKUS twice daily (BID) with placebo HandiHaler QD inhaler in 1:1 ratio in a cross-over manner for the study period (28 days for each period). At Visit 3 (Day 56), subjects will be asked to complete preference questionnaire 1 or 2. There will be no active treatment and subjects will continue to take their own prescribed COPD maintenance and rescue medication during the entire study period.

- Primary Outcome Measures
Name Time Method Percentage of Participants With Zero Errors After 28 Days of Inhaler Use in Each Treatment Phase (Primary Estimand: Hypothetical) Up to Day 56 A checklist for correct use of each inhaler was developed in Patient Instruction Leaflets (PIL's). Participants were guided by trained health care provider (HCP) to demonstrate correct use of inhaler. Baseline assessment was conducted when participant initially dispensed the inhaler. Second assessment was conducted after each 28day dosing period. Correct Use Check list was completed by HCP at each visit. Primary hypothetical estimand is the estimate of treatment effect of all participants who stayed on their randomized study device sequence and did not change their standard COPD maintenance medication device to one delivered via ELLIPTA, DISKUS or HANDIHALER, throughout both 28 day treatment periods. Participants could attend visit without the device/s they were randomised to, in which case correct use cannot be assessed as described in the protocol. Participants who completed error assessments for both randomized treatment groups and experienced no intercurrent events were included
Percentage of Participants With Atleast One Error After 28 Days of Inhaler Use in Each Treatment Phase (Primary Estimand: Hypothetical) Up to Day 56 Primary estimand is the treatment effect estimated in participants who stayed on their randomised study device sequence and did not change their standard COPD maintenance medication device to one delivered via ELLIPTA, DISKUS or HANDIHALER, throughout both 28 day treatment periods. The participant could attend the visit without the device/s they were randomised to, in which case correct use cannot be assessed as described in the protocol. For primary estimand, a sensitivity analysis using Cochran-Mantel-Haenszel test was performed on participants with discordant results. Only those participants who completed error assessments for both randomized treatment groups and experienced no intercurrent events were included
Percentage of Participants With Atleast One Error After 28 Days of Inhaler Use in Each Treatment Phase (Supplementary Estimand: Composite) Up to Day 56 Supplementary estimand estimated the composite effect of initial randomized treatment. A sensitivity analysis using the Cochran-Mantel-Haenszel test was performed on participants with discordant results. Participants who withdrew during period 2 were included in the analysis using early withdrawal data where available or imputation otherwise. Participants who experienced an intercurrent event in Period 1 were excluded from the analysis.
Percentage of Participants With Zero Errors After 28 Days of Inhaler Use in Each Treatment Phase(Supplementary Estimand: Composite) Up to Day 56 Supplementary estimand estimated the composite effect of initial randomized treatment. The analysis was performed using stratified exact logistic model. Participants were included in the model as fixed strata, treatment option was included in the exact statement and period included as fixed effects. Participants who withdrew during period 2 were included in the analysis using early withdrawal data where available or imputation otherwise. Participants who experienced an intercurrent event in Period 1 were excluded from the analysis.
- Secondary Outcome Measures
Name Time Method Change in Errors Per Participant for Each Treatment Group After 28 Days of Use Day 1 and Day 28 of each treatment group Assessment of errors was conducted by HCP trained in the correct inhaler use of the three inhalers based on the checklist of errors. The median number of overall errors made by per participant was assessed for ELLIPTA and DISKUS + HandiHaler both on Day 1 and Day 28 for each treatment group. The difference was calculated by subtracting values of Day 28 from Day1 for each treatment regimen. Only those participants who completed error assessments for both randomized treatment groups and experienced no intercurrent events were included.
Number of Errors by Type for Each Inhaler After 28 Days of Use in Each Treatment Phase (Primary Estimand: Hypothetical) Up to Day 56 The occurrence of each type of error for each inhaler (ELLIPTA, DISKUS or HANDIHALER) were evaluated based on the information collected in Correct Use Checklists. Primary estimand is the treatment effect estimated in participants who stayed on their randomised study device sequence \& did not change their standard COPD maintenance medication device to one delivered via ELLIPTA, DISKUS or HANDIHALER, throughout both 28 day treatment periods. The participant could attend the visit without the device/s they were randomised to, in which case correct use cannot be assessed as described in the protocol. For primary estimand, a sensitivity analysis using Cochran-Mantel-Haenszel test was performed on participants with discordant results. Only those participants who completed error assessments for both randomized treatment groups \& experienced no intercurrent events were included. The number of error is reported as NA for the type of error which was not applicable to the particular inhaler type
Change in Errors for Each Treatment Group in Participants With One or More Errors After 28 Days of Use Day 1 and Day 28 of each treatment group Assessment of errors was conducted by health care professionals trained in the correct inhaler use of the three inhalers based on the checklist of errors. The median of overall errors made by each participant was assessed for ELLIPTA and DISKUS + HandiHaler both on Day 1 and Day 28. The difference was calculated by subtracting values of Day 28 from Day1 for each treatment regimen. Only those participants who completed error assessments for both randomized treatment groups and experienced no intercurrent events were included.
Number of Participants With Atleast One Critical Error After 28 Days of Each Treatment Group Use (Primary Estimand: Hypothetical) Up to Day 56 A critical error was defined as an error that was most likely to result in no, or a significantly reduced amount, of medication being inhaled by the participant. Primary estimand is the treatment effect estimated in participants who stayed on their randomised study device sequence and did not change their standard COPD maintenance medication device to one delivered via ELLIPTA, DISKUS or HANDIHALER, throughout both 28 day treatment periods. The participant could attend the visit without the device/s they were randomised to, in which case correct use cannot be assessed as described in the protocol. For primary estimand, a sensitivity analysis using Cochran-Mantel-Haenszel test was performed on participants with discordant results. Only those participants who completed error assessments for both randomized treatment groups and experienced no intercurrent events were included.
